  There was a discussion on the behavior of a falling cat and
the "predatory swipe" as relating to moder animals, with
"gliding" and "cats" as search criteria. Last year, anyway.

<True. Well, maybe Archie dropped into the water head-first from

  Why? For diving birds, unless you're a duck, you need a good
deal of momentum going before you hit the water so that when you
_do_ plunge in, the fish can't get away fast enough. Herons and
anhingas stab down with the neck, and kingfishers and pelicans
are famous for power dives into the water and launching back out
(still using their original momentum) with their prey [if
they're lucky]. Meanwhile, ospreys have to flap on their way
back up.
